Brooks, Jones and Wyatt also admitted a breach of ECB Directive 3.4, which requires that all players abide by the ECB Anti-Discrimination Code. However, the CDC Adjudicator, Chris Tickle, decided that a reprimand would suffice in all five cases.
The cases came to light in the midst of the racism scandal that beset English cricket last year, and Rafiq - whose revelations of an institutionally racist culture at Yorkshire ultimately led to him testifying before a parliamentary select committee - reiterated after the CDC's decision that he was "ashamed and embarrassed" for his own anti-Semitic actions in a social media exchange dating back to 2011.
In a Facebook exchange, reproduced in full in the CDC judgement, Rafiq and his former England Under-19 team-mate Ateeq Javid joked about how a third, unnamed, team-mate was a "jew" for failing to pay his share of a bill at a restaurant.
"This summer, I unequivocally accepted a charge from the ECB regarding my antisemitic social media post from 2011," Rafiq wrote in the wake of the judgement.
"You will hear no complaint from me about the CDC's decision today. It is deserved and I fully accept this reprimand. I want to repeat my apology to the Jewish community. I remain ashamed and embarrassed."
Rafiq met with Holocaust survivors after the incident, including on this year's March of the Living at Auschwitz.
"I hope I have demonstrated over the past 10-11 months that I am trying to educate myself about the horrors and prejudice the Jewish community has historically - and continues - to face," he added.
"I will keep trying and I thank the Jewish community for the forgiveness and kindness that has been shown to me so far."
Following their disclosure, Brooks confirmed in a statement that he "deeply regretted" using the term and apologised "wholeheartedly".
